President Trump offered condolences on Thursday and promised to “tackle the difficult issue of mental health” after a former student opened fire at a Florida school, killing 17 people and injuring 14 more.

“It is not enough to simply take actions that make us feel like we are making a difference. We must actually make that difference,” Trump said in a sober White House address.

Trump, who said he will visit the site of the horrific carnage and meet with families and local officials and to continue coordinating the federal response, made no indication as to what the federal government would do to address the issue.

The White House cancelled a scheduled trip to Orlando Friday to pitch the President’s infrastructure plan.

It was unclear if Trump still planned to spend the weekend at his Mar-a-Lago resort, roughly 40 miles from the Parkland, Fla. school.

Trump made a similar address from the White House in October after 58 people were killed at a Las Vegas concert, the nation’s deadliest mass shooting.

The President has focused on mental health in his remarks following such tragedies, steering clear of any talk of gun control reform.

The President also issued a proclamation Thursday honoring the victims of the shooting.

“Our nation grieves with those who have lost loved ones,” it said, ordering American flags at public buildings across the country flown at half-staff.

“In times of tragedy, the bonds that sustain us are those of family, faith, community, and country. These bonds are stronger than the forces of hatred and evil and these bonds grow even stronger in the hours of our greatest need,” Trump said.
